METAL LATH.

Specification of Letters Patent. Patented All". 31, 1920.

Application filed February 4, 1919. Seria1 No. 2 75,013.

To all whom it may concern:

Be it known that I, STEPHEN SCANLON, a itizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Metal Laths, of which the following is a specification.

This invention relates to new and useful improvements in metal lathing, and has for its primary object to provide a structure of this nature which is of a. more or less flexible nature to permit of its adaptability to walls or surfazes of various contours.

A further object of the invention is t i:. eans therefor is employed.

further ob ect of the lnvention is to provide adevice which in addition to its use as a lath, is particularly adaptable to use as reinforcing means for concrete and analogous structures.

Referring to the drawings Figure l is a view in elevation of the lath, Fig. 2 is an edge View thereof, 7 Fig. is. a view showing one of the steps in the process of manufacture of the lath,

tllltl F at is a detail sectional View of a pori permit of its conforming to irregularities or tion of the lath.

In forming the lath, a sheet metal blank if) of rectangular form is employed. This 7 blank 10 is folded at equi-distantly .spaced points backwardly upon itself in opposite directions as shown at 11 in Figs. 2 and 3.

liter the blank hasbeen thus folded, the

same is subjected to pressure under which it compressed so that the several faces of the folded. portions lie in contact with each other as shown in Fig. 3.

"With the blank thus folded, it is submit ted to the action of suitable rollers to bend the same transversely of the folds as shown at 12 in Fig. 3, thus giving a concave-convex formation to each of the-folded portions.

After this operation, the blank is expand ed in any suitable manner; as shown in Fig. 2, to provide spaces or pockets 15'between the folds, the walls of which form suitable attaching means for plaster, cement or the like. The bottom wall of each of these pockets is curved as heretofore" described as at 12 which forms an additional anchorage for the plastic material which may be applied thereto.

As shown in Fig. 4, the blank is provided tures which form the means by which the lath is applied to the supporting structure through the medium of nails or the like. provide a metal lath in which attaching" These apertures are formed by cutting at its points of fold with a plurality of apernotches in the edges of theblankwhen fold ed as in Fig. 3.

From the foregoing it will b'e seen' that the present invention-provides a lath which is readily attachable to a suitable support, and at the same timea lath is formed by which the plastic material for which it is in: tended to support is firmly locked thereto.

Furthermore, a lath constructed in accordance with the present invention'is easily expansible to diiferent sizes, thus maklng 1t readily adaptable for the purpose designed.

The structure is also flexible to, a degree to curves in the surface to which it is applied.

Having thus described the invention, what folded upon itself'at equi-distantly spaced intervals to provide layers contacting throughout their entire area and adapted to be expanded to form oppositely disposed substantially triangular pockets, said pockeets tapering 1nwardly'fromthe1r outer open ends to provide gradually decreasing lop- .posed upper and lowe'r walls which meet at their nner POlIltBCl ends.
